MACHINE FOR MANUFACTURING JOINT-S CF UMBRELLA-RIBS.

SPECIFICATION forming part of Letters Patent No. 392,879, dated November13, 1888.

Application filed July 5, 1888. Serial No. 279,005. (No model.)

To all whom it may concern.-

Be it known that I, CARL PIEPER, a subject of the King of Prussia andEmperor of Germany, and a resident of the city of Weyer, in

5 the Kingdom of Prussia,German Empire, have invented certain new anduseful Improvements in Machines for Manufacturing Joints ofUmbrella-Ribs; and- I do hereby declare that the following is a full,clear, and exact description IO of the same.

My invention relates to an apparatus for making thejoint which connectsthe stretcher vertical sectional vicwsof the holding and pressingmechanisms. and 4 are detail views.

From the base or bed plate A extend upward three standards, B B B. Thecentral Figs. 3, r, r, r, r,

0 standard, B, is permanently fixed, and the other two standards, 13 B,are adjustable nearer to or farther from the central one to accommodateribs of different lengths. The central standard, B, carries the pressingand cutting mechanism, and the other two carry the mechanism for holdingthe rib while it is being operated upon. In front of each standard is ahopper, C, (see Figs. 3 and 4,) the bottom of which terminates in anarrow channel, through 0 which the ribs are guided and drop in correctposition into the track of the forwarding-slide D, from whence they arecarried singly by the forwarding-slide to a point where they drop into agroove in the bed on the joint- 5 eye, which has been previously cut bythe machine.

The operation of the forwarding-slide is effected by the cam-disks d d,(see Fig. 3,) which are carried by the main shaft E, jonrnaled in theframe of the machine, from which shaft motion is also imparted to theother working parts. The rib drops through the hoppers into the track ofthe slide in such a position with relation to the standards B B B (seeFigs. 3 and 4) that it is caught by the three slides D at both ends andin the middle and pushed forward. The three slides are connected to eachother, so as to move simultaneously, by means ofa bar, F, secured inclamps a a by set-screws b b, said clamps a being connected by setscrewsb to sliding rods G. (See Figs. 1, 3, and 3 The sliding connecting-rodsG move rectilinearly in ways above the bed-plate of the machine. Theirrear ends are formed with links which surround the main shaft E betweenthe cam-disks d and d,carried thereby. Each of these links is providedwith two rollers, cand 0, (see Figs. 2, 3, and 3%) the roller 0 forengagement with the disk (1 and the roller c for engagement with thedisk (1. The forwardingslides D are moved forward and backwardalternately as the cams of the disks (Z and d engage with the rollers aand c at every revolution of the shaft E.

The joint-eye is made from a wire, 0, the upperedge of which is grooved,as shown on an enlarged scale in Fig. 4". This wire is in a coil and isautomatically unrolled and fed as required. For this purpose itis-passed be- So tween two guiding-rollers, f, (see Fig. 5,) providedwith toothed wheels 9, (indicated diagrammaticallyin the drawings bydotted li nes,) which are engaged by a pawl, h, so as to receive anintermittent rotary motion in order 8 to feed them to the proper point.The pawl h is carried by theshort arm of a lever, H, having its fulcrumon the side of the standard B and its long arlnformed into a linkprovided with a roller, z, and surrounding a cam-disk, 0 6, carried bythe main shaft E. (See Figs. 2 and 5.) The wire a is moved forward therequired length by the rollers f into a groovein the lower cutter, k.

WVhen the wire is pushed forward by the ro- 5 tation of the rollers f,the required length projeets from said groove and is cut by the uppercutter, Z. This upper cutter, Z, is held in the sledge J, which slidesvertically in the central standard, 13, and receives its motion from thelever K. This leverhas its fulcrum on the standard B, Fig. 4, with itsshort arm engaging with a recess in the sledge J, audits long armprovided with aroller, K, which bears on the face of a cam-disk, Kcarried by the main driving-shaft E. As the shaft E revolvcs,the longarm of the lever K is raised audits short arm depressed, so as to forcedown the sledge J and the upper cutter, l, and cut off the end of thewire 6. The cutoff end of the wire 6 is pressed in'a cutting of thefeeder M, which is pushed forward by the cam-disk m,connected to theshaft E by means of the link M. This link surrounds the shaft E betweentwo camdisks, m, Fig. 2, and carries two rollers, m m Fig. 4, engagingwith the cam-disk m. At the forward motion of the cut-off wire end itpasses over a funnel-shaped opening between the holding-cheeks n 01,Figs. 4, 4, and drops into the opening, where it is caught by a tongue,0, below the holding-cheek n, 4, so that it stands vertically betweenthese holding-cheeks, after which the feeder M recedes. After thisoperation follows the motion of the forwarding devices for theumbrella-ribs, heretofore described. The rib lying in the track of theforwarding-slideD is pushed forward and drops into the slit between theholding-cheeks n n, Fig. 4, on the cut-off wire end 6, and a stamper, p,presses the rib into the groove of the wire piece 6, and both parts arepressed downward until the elastic tongueo engages with them. (See Fig.4 The press ing of the rib into the groove of the cut-off wire end isdone simultaneously with the cutting off of a new wire end. After theumbrella-rib x is pressed into the groove of the wire piece a theholding-cheeks a a of the side standards come into operation and holdthe umbrellarib 0a in the position shown in Fig. 5. After the stamper 1)has receded the movable ho1ding-cheek n is pushed forward by the camdisk N against the stationary cheek n, by which means the edges of thegroove in the piece 6 are turned in and pressed around the rib, forminga solid connection therewith, as shown in Fig. 4. At the same time thelower edges of the wire piece are der cutter is cut off and drops intothe slit of the feeder M, while a rib as is simultaneously pressed intothe groove of the wire piece 6, lying between the cheeksn nand on thetongue 0. The feeder M then moves forward and drops the wire piece 6into the slit.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for the automatic manufacture of umbrella-rib joints andthe simultaneous connecting of the same with the ribs, the combinationof the three standards B B B, the cutting apparatus Z K, connected withthe central standard, the pressing apparatus consisting of the stamper pand elastic tongue 0, the movable holding-cheek a in the standard B, andthe movable holding-cheek n in the standards B, all arranged andoperating substantially as herein described.

2. In a machine for the automatic manufacture of umbrella-rib joints andthe simultaneous connecting of the same with the ribs, the combinationof the elastically-arranged tongue 0, the slide N, carrying theholdingcheek n, the disk N, arranged on the shaft E, and the stamperp,all arranged and operating substantially as and for the purpose hereindescribed.

In testimony whereofl have signed my name to this specification in thepresence of two subscribing witnesses.

OARL PIEPER.
